` Lesesaa- Autographic Registers, of which the following' isa full,clear, and exact description.

My inventionrelates to autographic registers from whichpaper stripshaving a longitudinal series of alined "equi-distant perfo- .rations orfiling4 holes, are, after havin been' written upon, extracted and torn oand relates'more particularly to the type of registers 'illustrated anddescribed 1n myV application for Letters Patent of the United States,led ylVlarch- 27, 1.916, Serial No.

The object of my invention'is to provide an extracting mechanism whichincludesl a .vreciprocable' carrlerhav1ng rigid 4 pins mounted thereon,and a spring mounted channelA through which the strips of paper pass,and which impales the said strips upon said pins when the ling holes 'ofthe strips' come beneath and in register with the pins as said stripsare being extracted from the mechanism the channel drawing saidstripsol' of the pins lwhen said carrier is at the limit of its extractingmovement. These andother objects I accomplish by the means hereinafterfully described, Aand. as particu-` larlypointedout in thel claims.

rateateaoet. ae, rare! disposed platenthe side'edges of which aresecured to and connect the side-frames near 'their upper horizontaledges, and C the usual cover, which, in View of the fact that myimprovements donot affect the same, is not thoroughly illustrated insaid drawings.

The discharge end of the platen is i'ore- 'shortened and terminates asuitable distance back of the 'forwardmost portion of the verticallydisposed edges .of the ends of the side-frames, andbetween thetransverse vertical plane of the forward' transverse end edge of theplaten and the transverse vertical planel of the forwardmost part of*said side-frames a transversely disposed fiat horizontal plate or trayD is placed, whose hori- -zontal surface is slightly below that of saidplaten. The ends of tray D'hav'e blocks a,

a, securely mounted thereon which support the ends' of the tearing-bladeE,-whicli latter consists 'of a flat plate that bridges across the vrearportion 'of the tray from side-frame to side-frame, 4and has its forwardedge inclined vdownward at a suitable angle, subtantially as shown inFig. 2 of the drawings.

0n either side of its centerof length the tearing-blade has rigid' pinsG depending therefrom 'that terminate about half-way between'said bladeand tray D, and, preferably, have their extremities rounded, as

shown. These pins G areadapted toextend down through openings in the.upper and lower horizontal'plates and o of a floatingchann'el, whichplates are arranged between the tearing-blade andthe tray and extendfrom near one block a to the oppoby short vertically disposed tubesl 8into the upper ends of which the extremities of pins enter when thefloatingchannel is` at the Tubes 8 havel their lower serew-threadedendsreduced in diameter and passed through corresponding openings in` theforward ends of longitudinally disposed leaf-springs4 9, and nuts 10 arescrewed onto said threaded ends to secure the tubes to said springs.

Thevrear ends of springs 9 extend back under the platen a suitabledistance and are secured to the longitudinal members 12, 12`

of a U-shaped reciprocable frame that are held against the underside ofthe platen by screws 13, 13, (located near the forward edge of theplaten), and by screws 14, y14 (located near the rear ends of saidmembers), which pass through longitudinally elongated slots 15 15 and16, respectively, which limit the throw of said reciprocable frame. Theforward ends of said members 12 extend beyond the forward end edge ofthe platen and are bent downward slightly, and tray'D is secured to andsupported upon these forward ends, and

both said tray and said ends of members 12 are provided with openings upthrough which tubes 8 freely pass.4 Immediately in front of screws 14,14, members 12, 12, are connected bya tie-strip 17 and the reciprocableframe of which it forms a part is kept at the limit of its rearwardmovement by -1 means of a coil contraction spring 18, the ends of whichare, respectively, connected to ed upon a transverse rock-shaft 22,which is journaled in side-frames A, A, and has one.

end extended through its bearings and, provided with a crank 23 withwhich to rock it,

and between the bossof this crank and the adjacent side-frame shaft 22has a coilspring 24 surrounding the same, one end of which is secured tosaid side-frame and.

the other end to said shaft in any suitable manner. rlhe rockingmovement of shaft 22 is limited by means of an L-shaped arm 25 securelymounted thereon mediate its end at its'angle near the bearings of saidshaft in the side-frame opposite the crank. The lower branch of arm 25is adapted to engage the lower end of a segment shaped flange 26projecting from the last-mentioned side# frame when tray D is at thelimit of its rearward movement, and the extremity of the uppervertically disposed branch of said arm 25 is adapted to engage the rearsurface of said flange 26 when the tray is at the limit ofits forwardmovement.

When crank 23 is turned rock-shaft 22 is turnedsuiciently to cause arms20 to engage arms 19 and push the tray forward to the limit of itsforward movement and when the crank is then released, spring 24 on lsaidshaft 22 and spring 18, hereinbefore referred to, will return the trayto the rearwad limit of its'movement. When it does this, it isnecessary. for pins G, which have been previously passed through thefiling-holes in 'said paper strips, to have said strips releasedtherefrom, to prevent said strips from being buckled and carried to therear with said tray. This I accomplish by means of alongitudinally.reciprocable wedge 27 the upper fiat side of which isheld in sliding engagement with the underside of the platen' by means ofa screw 28 which extends down through a longitudinally ,elongated slot29 in the rearward extension30 of the wedge.

'The forward end of wedge 27 terminates (when at .the'limit of itsrearward m'ovement) a short distance to the rear of the forward end edgeof the platen.` A short distance back of this forward end the undersideof the wedge is beveled or incl-ined down' boss of arm 33 is providedwith a segmental depression or recess 35, and shaft 22 is provided witha pin 36 that projects into this recess 35 and is normally kept inengagement therewith by a coil expansion-spring 37 interposed betweensaid boss and a sleeve 38 secured on said shaft. may have the forwardends of segmental leafsprings 39 (whose rear ends are secured to theunderside of the platen) bear down upon the same. When shaft 22 isturned'to move the tray forward it moves independently of arm 33 untilpin 36comes in contact with the lower terminus of recess 35, or incontact with the end of a gage-screw 40 tapped through the lower portionof the boss of said arm, whereupon arm I 33 is rocked and propels wedge27 forward and moves bridge 31 and leaf-springs 9 downward, and thelatter move tubes 8 and plates 5 and c of the channel downward, and bythe time the -tray reaches the limit of its forward movement the plate dstrips the paper from pins G, and when this happens and the operatorreleases the pressure on crank23 the tray immediately returns to thelimit of its rearward movement, and `when pin 36 engages the up perterminus of recess 35 wedge 27 is moved If desired, bridge 31 Leashesrearwardly to the limit of its rearward move' ment.

It will-be noticeddthat, owing tothe manner inwhich arm 33 1s actuated,the rearv ward movement ofthe wedge is delayed` and f thus keeps thechannel in aposition "below pins G until after said pins have moved tothe rear of 'the filing openings of--the paper drawn. In orderto-prevent'the strips of tangular tension-plate 41 is employed whoseupper horizontal edge lextendsup through a recess in the forward edge ofthe platen and presses the paper toward cross-bar 7. The lower edge ofthis tension-plate is provided with a `knuckle that is loosely mountedupon a transverse stationary shaft 43 whose ends are secured in theside-frames, and the upper edge of said plate is kept pressing againstthe paper in the manner just stated, by a spring 44 whosev central yokebears rearwardlyagainst the plate and'whose coiled ends are wound aboutsaid shaft 43.

The continuous paper strips usedm conjunction with my improved registerhave a longitudinally arranged series vof equi-distant perforations thatare separated a d1stance rcorresponding to the length of the record orform printed thereon, whigh latter determines the length of stripwhich'is to be withdrawn. My improvements are adapted to engage theseperforations one at a time and to advance the strip just far enough toenable the operator to grasp the advance `edge of the strip and thenrelease it, leaving it to the operator to pull the st rip out of themachine a distance corresponding to the full length ofthe record orform, and to bring the next perforation in vertical register with theextracting pins. There are usually two of these series of perforations1n the paper strips, one near each side edge thereof, and

when the operator desires to extractthe strip he grasps the handle ofcrank 23 and turns rock-shaft 22, and arm 20 projecting therefromengages arm 19 and moves the reclprocable frame forward.` The tubes 8wlll have pushed the floating-channel upward so that pins G will havepassed through the perforations of the strips before the forwardmovement of said frame commences, therefore as `said frame movesforward, the pins that are mounted thereon, draw the strip forward adistance corresponding to the sweep o f arm 20. When the paper stripsreach th1s advanced point, wedge 27 will have depressedl springs. 9, 9,through the medium ofbridge 31,l and tubes 8 will move downward withthesesprings and the ioating channel will strip the paper olf of thepins, and the tray and conjunctive devices will return back to theirorlginal posltions, When the paper fra me againstl retraction. stantly,but lightly, urged toward teeth 47 .strip has been withdrawn until thenext er- 4 forations are in position to be 'enga e by pins Gr themachine will be ready tor the next extracting movement.

It may happen' that the operator having turned` crank'23 'to partiallyadvance the paper strips 'in the machine, suddenly notes that acorrection or addition must be made in the matter he has written. v'Thismakes it necessary to hold the U-shaped reciprocable frame in anadvanced position against the pull of springs 18 and 24. vFor thispurpose I provide a C-shaped pawl 46 fulcrumed mediate its ends to theunderside 'of the platen at a point back of the rearward'extension 30 ofthe-wedge when the wedge is retracted. One end f this pawl is pointedand adapt-ed to engage teeth 47 formed in the adjacent longitudinal edgeof the nearest member p12 of the frame, this end of the pawlbeingslightly longer than the distance from its pivotvto the teeth andextending forwardly of the pivot thereby holding the Tawl 46 is conby anattenuated spring 48 which extends rearwardly from its opposite end intocon- Y vtact withV the set-screw which secures the rear end of spring 18to the platen. In the V advancement of the frame the pawlv will rideover teeth 47 successively and will hold the frame at any desiredpartially advanced position when the` operator'stops turning crank 23.But to preventengagement between teeth 47 and the pointed end of thepawl during ordinary operation of the machine, I form the opposite endof the pawl with anoutwardly turned finger which rides -upon theinwardly exposed surface of a cam 45 projecting rearwardly' fromeXtension 30 of the wedge. From its root in extension 30 lthe inner faceof cam 45 parallels the toothed edge of member 12 for a dis* tancesomewhat less than thefull path of movement of the wedge. But at its tipthe cam diverges sharply from the member l2. rlhis divergence issuiicient to draw the4 pointed end of the pawl a considerable distanceawayfrom the toothed edge of member 12 when the rotation of crank 23 hasfullyv advanced the frame and wedge. parts in this .position theoperator removes his hand from crank 23 and the combined pull of springs18 and 24 jerks the frame and wedge back to retracted position beforethe light pressure of spring 48 can bring the pointed end of the pawlback to teeth 47. In other words, the finger on the pawl jumps from thetip of the cam to the root causing the pointed end of the pawl to skipby all the teeth 47 and seat itself in advance of the forward-tooth, asshown in Fig. 6. j

A plurality of superposed strips of paper are customarily used inmachines of this With the character, each strip having perforations forengagement by posts Gr. A careless operator will occasionally draw thevlowest strip ahead of the upper ones, so that the perfof rations of thelowest one move ahead ofthe perforations in the upper ones. This causesthe webs of the upper strips to overlie the perforations of the lowestone and necessitates advancing the upper strips upon the lowest one tobring all the perforations in register 'with each other and the posts.'To so advance the upper strips, when the frame is inretracted-position, requires separation` pose arm 33 is provided with ahandle 34 and slidably mounted on shaft 22, so that it 'can move to theleft-viewing Fig. l-suiiiciently to clear pin 36 from recess 35 andpermit thev arm to be rotated forwardly from the position shown in Figs.1 and 5, the expansion spring 37 yielding `horizontally to permit thismovement. To facilitate such action of the v parts the shoulder of metalformed at the upper forward end of recess is rounded as' shown, inoutline in frontV elevation, in Fig. 1, and, by shading in sideelevation, in. Fig. 5, and .handle 34 is twist-ed slightly to presentits broad surface conveniently to the left thumb o f the operator. Thisforward movement of'arm 33 carries wedge 27 forward independently ofshaft 22 and the reciprocable frame-which are at rest in retractedpositionand hence results in freeing the strips. of'paper by loweringtubes 8 through the medium of bridge 31 and springs 9. The severalstrips may now be shifted relatively to bring their perforations inregister. Should it happen that the apertures, when brought intoregister with each other, stand somewhatforward of posts G, the operatorwill not wish to buckle the strips by attempting to push them backwardin the machine untilthe alined apertures shall register below the posts.Instead he can advance the posts into vertical alinement with theapertures by slightly rotating crank 23 and as he releases the crankpawl 46 will engage one of teeth 47 to hold the frame and posts-in thispartially advanced osition; the operator may then grasp hand e 34 andretract wedge 27, thereby impaling all the strips on posts G andreturning pin 36 to its normal position in recess 35. The parts willremain in this sli htly advanced position leaving the strips at on theplaten, until the operator completes his writing and rotates crank 23mesma to advance the frame and wedge the full stroke.
